Description
The 2/2-way solenoid valve MVA.34.MS.12.N.RZ.20 switches fluids electrically, with no manual intervention at the line. It operates in the range 0 to 12 bar at nominal size DN 20 and is force pilot operated.
Benefits
- Closed at rest: on power failure the valve shuts off up to 12 bar.
- Force pilot operated from 0 bar: switches without minimum pressure up to 12 bar at DN 20.
- Internal parts in brass and stainless steel, housing in brass and seat in brass and stainless steel, DN 20.
- Medium temperature -20 to 85 °C with NBR seals, G 3/4 port.
- Connection for 12 V DC: connector socket, industrial standard type A, EN 175301-803-A, degree of protection IP 65 (with connector socket fitted), type MVA.34.MS.12.N.RZ.20.
Applications
It is used in plant engineering, process technology and filling systems. Medium temperatures of -20 to 85 °C are permitted at an ambient of -10 to 50 °C. The NC rest position suits any G 3/4 line that has to close on power failure.
